Is Sodium Cocoamphopropionate natural?

Mostly. Coconut fatty acid is condensed onto an aminoethylethanolamine backbone extended with an acrylic-acid-derived propionate arm, both explicitly petrochemical per this site's method.

How we scored it

CocoCO-NH-C2H4-N(C2H4OH)-C2H4-COONa ~380 Da = coco acyl+Na natural 206 Da vs AEEA backbone+acrylate arm petrochemical 174 Da; 206/380 = 0.54.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Made by acylating coconut fatty acid onto aminoethylethanolamine (AEEA), then reacting with acrylic acid to build the propionate arm and neutralising with sodium. The coco fatty portion is natural; the amine and acrylate portions are petrochemical.

In plain English

A mild, foam-boosting amphoteric surfactant used in cleansers and shampoos. It is made by reacting coconut fatty acid with synthetic amine and acid building blocks, then neutralising with sodium.

CosIng definition: beta-Alanine, N-(2-aminoethyl)-N-(2-hydroxyethyl)-, N-coco acyl derivatives, monosodium salts
